The aim of this study will be to evaluate the non-inferiority of implants produced by additive manufacture loaded in 30 days when compared with those loaded in 90 days, in relation to marginal bone loss, after 01 (one) year of follow-up
This randomized Split-mouth clinical study of non-inferiority will monitor for one year partially edentulous patients in the posterior region of the mandible or maxilla, rehabilitated with 2 implants (AM) in the same Arch to evaluate the success rate of the implant, one loaded at 30 days after installation and the other at 90 days. Changes in marginal bone level and osseointegration success will be evaluated, with visits and data collection in 0 days (baseline), 30 days, 90 days, 6 months and 1 year

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Loading in 30 days | Experimental | Implant allocated to the study arm will be restored with a temporary restoration after 30 days of implant placement, that will be replaced with definitive restoration after 90 days of implant placement. |
|
| Loading in 90 days | Active Comparator | Implant allocated to the study arm will be restored directly with the definitive restoration after 90 days of implant placement. |

|---|---|---|---|---|
| Dental implant produced by additive manufacture | Device | In a split-mouth setup, each participant will receive two implants in the posterior region of the mandible or maxilla. After implant insertion, one implant will be randomly allocated to receive Temporary restoration after 30 days and definitive restoration after 90 days |
| Measure | Description | Time Frame |
|---|---|---|
| Marginal Bone Loss (MBL) | Digital periapical radiographs will be taken at the implant installation (baseline) after 1 year. The radiographs will be taken using the parallelism technique with a positioner that supports the digital sensor in order to standardize the radiographs. | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Implant success rate | The success rate or failure of each implant in clinical and radiographic findings will be classified using the success criteria defined by Buser et al. (1990)

either the operator or the patient will be blinded for the primary outcome
|
| Dental implant produced by additive manufacture | Device | In a split-mouth setup, each participant will receive two implants in the posterior region of the mandible or maxilla. After implant insertion, one implant will receive definitive restoration after 90 days |
|
| 1 year |
| Modified Plaque Index (mPI) | Modified Plaque Index (Mombelli, Van Oosten Et.Al 1987): Scoring Criteria: Score 0: No detection of plaque Score 1:Plaque only recognized by running a probe across the smooth marginal surface of the implant Score 2: Plaque can be seen by the naked eye. Score 3: Abundance of soft matter. The changes in Modified Plaque Index (mPI) will be monitored at 0 days (baseline), 30 days, 90 days, 6 months, and the final endpoint is one year | 1 year |
| Modified Bleeding Index (mBI) | Modified Sulcus Bleeding Index (Mombelli, Van Oosten Et.Al 1987): Scoring Criteria: Score 0: No bleeding when probe is passed along the gingival margin. Score 1: Isolated bleeding, spots present. Score 2: Blood forms a confluent red line on margins. Score 3: Heavy or profuse bleeding. The changes in Modified Bleeding Index (mBI) will be monitored by a blinded calibrated examiner at 0 days (baseline), 30 days, 90 days, 6 months, and the final endpoint is one year | 1 year |
| Pocket probing depth (PPD) | Pocket Probing Depth (PPD) will be measured by a blinded calibrated Examiner, and The changes in Pocket Probing Depth (PPD) will be monitored at 0 days (baseline), 30 days, 90 days, 6 months, and the final endpoint is one year | 1 year |
| clinical attachment level (CAL) | Clinical attachment level (CAL) will be measured by a blinded calibrated Examiner, and The changes in clinical attachment level (CAL) will be monitored at 0 days (baseline), 30 days, 90 days, 6 months, and the final endpoint is one year | 1 year |
